any provision of this Agreement, Licensor reserves the right to terminate this

laws of the State of New York applicable to contacts made and performed entirely
therein.

         13. Entire Understanding. This Agreement contains the entire
understanding of the parties hereto relating to the subject matter herein
contained, and supersedes any and all prior agreements or understandings
relating to the subject matter hereof. Without limiting the generality of the
foregoing, this License Agreement amends, restates in its entirety and
supercedes that License Agreement dated March 13, 1997 by and between Licensor

the party sought to be charged therewith.

         14. No Waiver. No waiver by either party, whether express or implied,

shall constitute a continuing waiver or a waiver of any other provision of this
Agreement, and no such waiver by either party shall prevent such party from
enforcing any and all provisions of this Agreement or from acting upon the same
or any subsequent breach or default of the other party. No waiver of any
provision hereunder shall be effective unless it is in writing signed by the
against whom enforcement thereof is sought.

         15. Separability. The provisions set forth in this Agreement shall be
considered to be separable and independent of each other. In the event that any
provision of this Agreement shall be determined in any jurisdiction to be
unenforceable, such determination shall not be deemed to affect the
enforceability of any other remaining provision and the parties agree that any
court making such a determination is hereby requested and empowered to modify
such provision and to substitute for such enforceable provision such limitation
or provision of a maximum scope as the court then deems reasonable and
judicially enforceable and the parties agree that such substitute provision
shall be as enforceable in said jurisdiction as if set forth initially in this
Agreement. Any such substitute provision shall be applicable only in the
jurisdiction in which the original provision was determined to be unenforceable.

         16. Relationship of the Parties. Nothing contained herein shall be
construed to place the parties in the relationship of partners or joint
venturers and neither party shall have the power to bind or obligate the other.

         17. Survival. Unless otherwise provided, the obligations of the parties
hereto shall survive the termination of the term of this Agreement.

         18. Arbitration. All claims, demands, disputes, controversies,
differences or misunderstandings between or among the parties hereto or any
other persons bound hereby arising out of or by virtue of this Agreement, shall
be submitted to and determined by arbitration in the City of New York. If the
parties to a dispute arising out of this Agreement are unable to agree on an
arbitrator within 10 days after any party shall have given written notice to the
other that it desires to submit any issue to arbitration, then the American
Arbitration Association shall be designated by any party to appoint an
arbitrator and to arbitrate the matter under its rules. The award of the
arbitrator shall be made in writing, shall be within the scope of this
Agreement, shall not change any of its terms or conditions, shall be binding and
conclusive on all parties, and shall include a finding for the payment of the
costs of the arbitration proceeding (including reasonable attorneys' fees). It
is further agreed that judgment of a court having jurisdiction may be entered
upon the award of the arbitrator.

         IN WITNESS WHEREOF, the parties have caused this Agreement to be duly
executed as of the day and year first above written.
